Any idea how to write a Validation Rule, that prevents the user from creating more than one record a day.
I have one Object called (Stundenkonto__c)(Stundenkonto__c)
it shows a Month in Timetracking.
I have a Object calldcalled (Zeiteintrag__c)(Zeiteintrag__c)
it is the Master Detail of (Stundenkonto__cStundenkonto__c
)
So the User should only be able to create only one (Zeiteintrag__cZeiteintrag__c
) Record a day.
